SWABIAN INSTRUMENTS is a private owned business in Germany that develops and manufactures software and hardware for data acquisition and instrument control. Swabian designs and manufactures data acquisition and signal generation systems for research and industry. Our systems are easy to use and packed with useful features. This is achieved by shifting some of the hardest tasks from the hardware to the software level. This makes the systems flexible and extendable, which is called “Software Defined Data Acquisition”. Swabian’s systems cover a frequency range from DC to 50 GSa/s. Swabian Instrument’s commercial product “Time Tagger 20” is emerging as one of the most powerful data acquisition tools used by the physicsresearch community from quantum optics to bio physics.
